Cheap parts can cause this problem. Also incorrect installation of the pads can cause this also. Lubricating the back of the pads with a high temp grease can and will prevent this. I suspect the pads were incorrectly installed.

a lot of the noises are related to brake pad material. in this economy, we tend to go with cheaper parts. sometimes, this is a result. when you replace the pads, make sure you use a good quality pad. it will cost more, but will give you less headaches.

When they dry out is the noise still present. What happens if you apply the brakes a little harder? Do you have brake pad material left or is it time for another brake job. If you're not sure swing on in and we'll look at it for you. Happy Holidays.
